The invention relates to the technical field of refrigerators, and discloses a three-drawer leveling structure used for a refrigerator. The refrigerator comprises a left drawer, a middle drawer and a right drawer. An inverted-U-shaped supporting frame is arranged between the left drawer and the right drawer, and the middle drawer is located in the supporting frame. Rolling wheels are correspondingly arranged at the outer sides of the two side walls of the supporting frame. The left drawer and the right drawer are matched with the rolling wheels of the supporting frame correspondingly. The three-drawer levelling structure comprises two protruding parts. The two protruding parts are symmetrically arranged at the inner sides of the two side walls of the supporting frame. The two protruding parts deviate from the side walls where the protruding parts located and extend inwardly, and limiting parts are correspondingly arranged at the two side walls of the middle drawer and are matched with the protruding parts. According to the three-drawer levelling structure and the refrigerator of the three-drawer levelling structure, by symmetrically arranging protruding parts at the side walls of the supporting frame and correspondingly arranging limiting parts at the two side walls of the middle drawer, the upper end face of the middle drawer and the upper end faces of the left drawer and the right drawer are located in a same plane by matching between the protruding parts and the limiting parts, so that stability and attractiveness of products are improved. The invention further provides the refrigerator of the three-drawer levelling structure.
